A membrane electrode assembly includes a rod-shaped or tubular anode, an anode terminal connected to the anode, a cathode disposed at a position apart from the anode so as to face the anode, and a membrane that separates the anode from the cathode. The cathode includes a line-shaped or strip-shaped cathode-supporting portion and a cathode claw that extends to the left, right, or both left and right from the cathode-supporting portion and that is curved along an outer periphery of the anode. The cathode-supporting portion and the cathode claw form an anode-holding portion of the cathode. The membrane includes a membrane strip, and the membrane strip is disposed on the cathode claw to be in contact with the cathode claw so that the anode is held by the anode-holding portion of the cathode with the membrane strip therebetween.

Membrane electrode assembly and electrolyzed water production device using the same

The present invention provides: a membrane-electrode assembly having a first electrode having a shape of a rod-form or a cylindrical-form, a strip-form diaphragm covering the periphery of the first electrode, and a second electrode disposed on a surface of the strip-form diaphragm; an electrolytic unit containing the membrane-electrode assembly; an electrolytic water ejecting apparatus containing the electrolytic unit; and a method of sterilization using the membrane-electrode assembly.

A zero-gap type electrolytic cell 11 characterized as having a hydrophilic liquid-permeable material 16 interposed between an ion-exchange membrane 12 and a gas diffusion cathode 17. The reaction product passes through the liquid-permeable material and disperses toward edges of the liquid-permeable material before being withdrawn. Hence, the withdrawal direction for the target reaction product is not opposite the feed direction for the reactant gas.
